The company said that it plans to cut an additional 5,000 jobs beyond its most recent round of layoffs, and these new efforts will cost the company $300 million. Despite this new round of cost-cutting efforts, the company said it expects to report an operating loss in the fiscal second quarter as well.

To compound matters, unexpected delays will push the launch of RIM’s first BlackBerry 10 smartphone back to the first calendar quarter of 2013. RIM previously said the first handset to run its next-generation OS would be released later this year.

RIM CEO Thorsten Heins confirmed on the company’s earnings call that it intends to launch a full-touchscreen BlackBerry 10 device in the first quarter next year, and that launch will be followed by the launch of a QWERTY smartphone shortly after. New details surrounding both models leaked earlier this week. Heins also said RIM is exploring opportunities to license BlackBerry 10 to other companies.

RIM sold 7.8 million BlackBerry smartphones during the first fiscal quarter of 2013, down 41% from the same quarter a year earlier, and the firm’s cash on hand rose to $2.2 billion.

The company’s stock plummeted more than 17% in after-hours trading on the news. RIM’s full earnings release follows below.
